Jacoco instrumentation error

In a Java project build, I was getting an error complaining about Jacoco failing to instrument a particular class. Looking at the complete stack trace of the error, it was an exception about index going out of bounds.

Caused by: java.lang.ArrayIndexOutOfBoundsException: 6
at org.jacoco.core.internal.BytecodeVersion.get(BytecodeVersion.java:41)
at org.jacoco.core.instr.Instrumenter.instrument(Instrumenter.java:87)
at org.jacoco.core.instr.Instrumenter.instrument(Instrumenter.java:123)

Fortunately, a little bit of search showed that it is related to Java. My initial version of Java was '1.8.0.121'. The fix was backported to '1.8.0.172'. I also had '1.8.0.192' installed. So, I switched versions and tried a clean build. It worked fine.
